To all whom it may coit'cem Be it known that I,,E1 GAR K;

Massachusetts, have j invented an Improve ment 1n Lanternsspecification: t

1 This invention "was a to improvements in lanterns to burn hydrocarbonsor fluid produc tions'fromcoal'oil has for itsobject such constructionof a lantern that it will burn whether stationary or being moved, and unj der varying conditions and movem air outside the lantern.

Fig.

I In the drawing, asdesignatesthe receptacle forthe kerosene or other oil. bis the burner; 0, theshaft to raise or-lower the wick, and d the elevated cone surroundingthe burner, all jof, usual construction. M plate e extends laterallyfrom, near the base :of' the burner to a ring, f, within the upper endof which is placed the globe 9'. Outside this ring is placed adeflectonh, substantially such'asshown in my Patent No'.,l44,200,- toforce the air into the openings twlienjthe lantern is being swungorlifted,thereby counteractifng the descendingmotionofthe air within theglobe, substantially such as: shown in my air feedingring is differentlyconstructed, and is not providedwith holes, asthereinshown.

:L o obvietth sI-ha ma a se esofa x Q iliary openings, 7:,in thelingfiimlnediately ,-ja b e p in s T earri tit ed Ewithin the ring f,separatesUthesetWo series of openingsk "i I'This feed-ringis shown bentor waved .at its interior portion,;to present althecurrent downward asto assist in'ffeeding The ,curved bottom Patent no. 144,200; butinithis'iiistanoe the" nan construction shown in the: Patent,,

1 lantern, such air is drawn 'theiefrdnitooQneeir ring rest upon thebottom plate, thereby leaving a series of radial passages opening towardthe center of the burner. The air admitted at the openingsi is ledthrough the passages under the feed-ring to the interior of the burnerto supply it with air. Should the wind blow into such openings, thecurrent will be checked a hole which may be made through the bottomplate for the passage of a match or other or retarded, and the air whichdoes not pass up through the center of the burner will be forced, acrossunder the open cone d, and, impinging upon the upper curved faces of thefeed-ring, will rise upward between the cone and-.theinterior of theglobe without impinging directly upon the outside of or blowing directlyacross the top of the burner. When the, air outside the lantern has sucha motion with relation to the deflector as to suck the air from theinterior outward, then, to supply air to the interior of the lantern andsupport combustion at the burner, I have provided the ring with a seriesof auxiliary air-passages, k, which admit air from the outside as theair from the inner side is exhausted through holes. This is a mostimportant requisite of this my invention, as to the maintenance ofcombustion at the burner, and to keep at that point a proper supply ofoxygen.

When,,however, the atmosphere is considerably disturbed outside thelantern, air coming in at the openings k isv apt to deflect the smoke orflame against the interior of the globe and blacken it. To obviate thisI have placed above the feed-ring a smoke-preventing ring, 17. Theflange g of this ring rests against the ring fat its interior, above thepassages 70, and air entering such passages is checked by the depressedportion r of the ring 1;, and thence passesiuto the interior of thelantern at an intermediate position between the passages 7c and; theburner, whereby the body of air so. discharged is caused to ascend in amore central position, so that it does not defl'ect the flame and smokeagainst the interior of the globe opposite the burner, as would be thecase under some conditions of the air outside the. antern, if the ring12 wereomitted.

The bottom plate 0 is shown in Fig. I as concaved between its raisedcenter and outer edge,

and it is provided with suitable openings 3, for

the discharge of water which may fall upon the bot om P a small-sizedlanterns, however, I prefer to omit the raising of the bottom plate atits center, andshape it as shown in Fig. 7, wherein the bottom plate isshaped substantially as the interior. of a. saucer, with the exceptionof ai s,rnall ann lar bead or rim, 5,, which acts. w tli .an .;-eircessof air to raise it, and cause part of it to pass upward the globe out sde of the cone. With this form of plate, I prefer to provide it atbottom with a greater At itsnumber of holes than at Fig. 2, and thepassages 0' will in such case be somewhat contracted. This bottom platemight bemade flat, it being provided outside the cone with an elevatedannular ring, to operate as before described of Fig. 7.

Fig. 4 represents a modified form of feedring, the flange being waved asthe interior portion of the ring, Such a ring would only cover a portionof the holes of the lower series located as at i, and those not coveredwould admit air between the feed and smokerings.

In Fig. 2 I have shown a device, t, 'to cover 1 fcomposed. of aplate,conc'aved at its. side the top of the globe, as at u,- and itis'provided with a.

flange, v, and below it. is an auxiliary flange, w,of greaterdiameterthan flanges. Between, this flanged plate u and the topof theglobe and the flange w is an open space, 9, through which the air in thelantern ,rises and passes .111;. The plate a and theflanges t and wareso shaped with relation to eachother as to prevent too much air passinginto the globe from the top.

In Fig. 6 the bail a; of the lantern is shown as connected with a frame,3 pivoted to eyes 6., sustained by the oil reservoir or lanternbase. Aportion, 7, of the .frame extended, across the top part of the1antern,and provided with a projection, 8, engages the top, a. portionof the projection entering adepressed part of the cover, or vice versa;thereby hold ing the frame and top lockedjtogether. The openings 10(seeFig. 2 ).i'n the deflector permit. the passage of water. down throughthem.

. The rim 11, between th 'tttwmprae and the top of the receptacle (it,adds to, the strength or rigidity of the lantern. tniay, however, beomitted. f p

The devices herein described for supply ing and regulating the passageof air to the flame may be used in otheriapparatus wherein hydrocarbonoils are consumed.
